Default Throw Out Bearing?

I was parking my C4 last night while my friends waited for me outside of it. One of them asked me, as I got out of the car, how many miles I have on the car (91k) and then said that it sounds like my throw out bearing is going.

Now my clutch is 4 days old. Isn't the throw out bearing part of that new clutch? Or am I off track here and need some learnin'. This something else I need to get remedied?

Thanks all.

The transmission will make a whir that is mistaked by most as a throwout bearing. You may have read about the noise the single mass set-ups have.....the stock does the sames thing but is quiet do to the bushings in the flywheel......I have heard many that sound like super chargers...and some that make no noise............ A whiring noise is heard sometimes if you c-brace is not perfectly tight...Making the alignment of you drive line off a little... This is hard because sitting under load the bolts will seem tight, put a jack under the tail af the tranny and go up a little...you may find some room to make the bolts tighter.........More info can be found about this and some plates to prevent twisting at z51performance........It might be fine though....just tell your friends its a race thing they wouldn't understand..that's what I do...

It not part of it, but by all means should be replaced when the clutch is done. Ask your shop or check your bill to see if yours was replaced.

If you put on a new pressure plate it comes with a new throwout bearing. Unless the shop removed the bearing and put your old on in there it should have been replaced. The only reason they would swap them is if they ordered the wrong year's setup. The late ZF throwout bearing (I think it is '94-96 but may be '93-96) will not slide onto the larger diameter early model output shaft collars ('89-92/93) on the front of the tranny.
